Rand des Bodenblechs verspannbar ist.Edge of the floor panel is clamped.
Eine solche Bodenblechbefestigung ist aus der DE 44 46 223 C1 bekannt. Der Bodenrahmen des Schaltschrankes ist dabei aus vier Profilabschnitten zusam- mengesetzt. Die Profilabschnitte sind im wesentlichen U-förmig ausgebildet, wobei an einem horizontalen Auflageabschnitt zwei senkrecht abstehende Profilseiten angeschlossen sind . Die Profilseiten sind an ihren Rändern abgekantet. Damit entsteht an dem innenliegenden Profilabschnitt ein horizontaler Anlageflansch, auf den Bodenbleche plan aufgelegt werden können. Die ROänder der Bodenbleche können mit dem Anlageflansch mittels Spannklammern verbunden werden. Die Spannklammern sind als U-formige Bauteile mit zwei parallelen Schenkel ausgebildetSuch a floor panel attachment is known from DE 44 46 223 C1. The base frame of the control cabinet is made up of four profile sections. The profile sections are essentially U-shaped, two vertically projecting profile sides being connected to a horizontal support section. The profile sides are folded at their edges. This creates a horizontal contact flange on the internal section of the profile, on which floor panels can be placed flat. The edges of the floor panels can be connected to the system flange using clamps. The clamps are designed as U-shaped components with two parallel legs
Zwischen den beiden Schenkeln befindet sich der Rand und der Anlageflansch. Einer der beiden Schenkel tragt eine Schraube, mittels der das Bodenblech mit dem Anlageflansch an dem zweiten Schenkel verspannt werden kannThe edge and the contact flange are located between the two legs. One of the two legs carries a screw, by means of which the base plate can be clamped to the contact flange on the second leg
Es ist Aufgabe der Erfindung, eine Befestigung der eingangs erwähnten Art zu schaffen, mittels der das Bodenblech und der Bodenrahmen zuverlässig auf das gleiche elektrische Niveau gelegt werden können.It is an object of the invention to provide a fastening of the type mentioned at the beginning, by means of which the floor panel and the floor frame can be placed reliably at the same electrical level.
Diese Aufgabe wird dadurch gelöst, daß sich der erste Schenkel mittels Schneiden und/oder Spitzen von Kontaktierungselementen von an dem Anlageflansch abstutzt, und daß die Schraube im elektrisch leitenden Kontakt mit dem Rand des Bodenblechs steht.This object is achieved in that the first leg is supported on the contact flange by means of cutting and / or tip contacting elements, and in that the screw is in electrically conductive contact with the edge of the base plate.
Die Schneiden und/oder Spitzen graben sich beim Verspannen der Spannklammer in den Anlageflansch ein. Insbesondere kann eine auf dem Anlageflansch aufgebrachte Lackschicht durchstoßen werden, so daß ein sicherer elektrischer Kontakt zwischen der Spannklammer und dem Anlageflansch entsteht. Die elektrisch leitende Verbindung zu dem Bodenblech wird über die Schraube hergestellt Diese gelangt beim Verschrauben in innigen Kontakt mit dem Bodenblech. Infolge des Anziehens der Schraube reibt die Schraube über die Oberseite des Bodenblechs und vermag damit einen sicheren elektrischen Kontakt herzustellenThe cutting edges and / or tips dig into the contact flange when the clamping clamp is clamped. In particular, a layer of lacquer applied to the contact flange can be pierced, so that a reliable electrical contact between the clamping clip and the contact flange is created. The electrically conductive connection to the floor panel is established via the screw. When screwed in, this comes into intimate contact with the floor panel. As a result of tightening the screw, the screw rubs over the top of the base plate and is therefore able to make a reliable electrical contact
Nach einer bevorzugten Ausgestaltungsvaπante der Erfindung ist es vorgesehen, daß aus dem ersten Schenkel wenigstens zwei als Zungen ausgebildete Kontaktierungselemente freigestanzt und in Richtung auf den Anlageflansch hin abgebogen sind, und daß die Zungen endseitig quer zu ihrer Längsachse abge- schnitten sind, so daß sich Schneiden bilden. Mit dieser einfachen Maßnahme ist eine kostengünstige Fertigung der Spannklammern möglich.According to a preferred embodiment of the invention, it is provided that at least two tongues are formed from the first leg Contacting elements are punched out and bent in the direction of the contact flange, and that the tongues are cut off at the ends transversely to their longitudinal axis, so that cutting edges are formed. With this simple measure, inexpensive manufacture of the clamps is possible.
Wenn vorgesehen ist, daß der Verbindungsabschnitt Versteifungsrippen aufweist, die senkrecht zu den Schenkeln stehen, dann ist eine Aussteifung der Spann- klammer erreicht. Insbesondere wird dadurch verhindert, daß sich der Verbindungsabschnitt beim Anziehen der Schraube verbiegt.If it is provided that the connecting section has stiffening ribs that are perpendicular to the legs, then a stiffening of the tensioning clamp is achieved. In particular, this prevents the connecting section from bending when the screw is tightened.
Zusätzlich kann es dabei vorgesehen sein, daß sich die Versteifungsrippen über die zwischen dem Verbindungsabschnitt gebildeten Kantenbereiche hinaus erstrecken. Diese einfache Maßnahme verhindert, daß die Schenkel beim Verspannen derIn addition, it can be provided that the stiffening ribs extend beyond the edge regions formed between the connecting section.

Spannklammer U-förmig aus einem Stanz-Biegeteil gefertigt ist, und daß der dem Bodenblech zugewandte Schenkel mit einer wulstartigen Verdickung versehen ist, in den die Gewindeaufnahme für die Schraube eingearbeitet ist. Damit kann die Spannklammer aus einem relativ dünnen Blechmaterial gefertigt werden. Eine ausreichende Gewindelänge wird dabei mittels der Verdickung sichergestellt.Clamp is made U-shaped from a stamped and bent part, and that the leg facing the base plate is provided with a bead-like thickening, in which the thread holder for the screw is incorporated. This allows the clamp to be made from a relatively thin sheet material. A sufficient thread length is ensured by means of the thickening.
Zur verbesserten elektrischen Kontaktierung zwischen dem Bodenblech und der Schraube kann die Schraube stirnseitig mit Vorsprüngen versehen sein. Diese graben sich beim Anziehen der Schraube in die Oberfläche des Bodenbleches ein.

A screw 17 can be screwed into the thread receptacle. The lower leg 1 2 has three contacting elements 1 6. The
Anordnung der Kontaktierungselemente 1 6 kann im einzelnen der Fig. 2 entnommen werden . Aus dieser Darstellung ist ersichtlich, daß die Kontaktierungselemente zungenartig aus dem Schenkel 1 2 freigestanzt sind. Die Enden der Kontaktierungselemente sind dabei schräg zu ihrer Längsrichtung ab- geschnitten, so daß sich dreieckfόrmige Spitzen ergeben. Die Kontaktierungselemente 1 6 sind im Bereich ihrer Spitzen in Richtung zu dem oberen Schenkel 1 1 hin abgebogen. Dabei ragen scharfkantige Schneiden der Kontaktierungselemente 16 in den von der Spannklammer 10 umgebenen Aufnahmeraum. Die Spannklammer 10 weist drei Kontaktierungselemente 1 6 auf. Das mittlere Kon- taktierungselement steht dabei in Flucht zu der Mittellängsachse der Schraube 1 7.The arrangement of the contacting elements 1 6 can be found in detail in FIG. 2. From this illustration it can be seen that the contacting elements are punched out tongue-like out of the leg 1 2. The ends of the contacting elements are cut off obliquely to their longitudinal direction, so that triangular tips result. The contacting elements 1 6 are bent in the area of their tips towards the upper leg 11.

Zur Aussteifung der Spannklammer 1 0 sind Aussteifungsrippen 14 verwendet. Die Aussteifungsrippen 14 verlaufen senkrecht zu den Schenkeln 1 1 , 1 2 über die gesamte Höhe des Verbindungsabschnitts 1 3. Im Anschluß an den Verbindungsabschnitt 1 3 sind die Rippen über den Kantenbereich, der sich zwischen dem Verbindungsabschnitt und den Schenkeln 1 1 , 1 2 ergibt, geführt und erstrecken sich teilweise über die Schenkel 1 1 , 1 2. Die Aussteifungsrippen 14 sind als Ausprägungen ausgebildet, die aus dem Material der Spannklammer 10 herausgedrückt sind .To reinforce the clamp 1 0 stiffening ribs 14 are used. The stiffening ribs 14 run perpendicular to the legs 1 1, 1 2 over the entire height of the connecting section 1 3. Following the connecting section 1 3, the ribs are over the edge region that results between the connecting section and the legs 1 1, 1 2 , guided and extend partially over the legs 1 1, 1 2. The stiffening ribs 14 are formed as expressions which are pressed out of the material of the clamping clip 10.
In der Fig. 3 ist ein Anwendungsbeispiel der erfindungsgemäßeπ Spannklammer 10 dargestellt. In dieser Zeichnung ist ein Bodenrahmen 20 dargestellt, der einen horizontalen Auflageabschnitt 21 aufweist. Von dem Auflageabschnitt 21 sind zwei Profilseiten 22, 23 rechtwinklig abgekantet. Von der inneren Profilseite 23 ist ein Anlageflansch 24 abgebogen. Auf diesem kann ein Bodenblech 25 mit seinem Rand aufgelegt werden. Das Bodenblech 25 kann mit dem Anlageflansch 24 mittels mehrerer Spannklammern 10 verspannt werden. Dabei wird die U-förmige Spannklammer so montiert, daß der Rand des Bodenbleches 25 und der Anlageflansch 24 zwischen den beiden Schenkeln 1 1 , 1 2 zum Liegen kommt. Beim Anziehen der Schraube 1 7 werden das Bodenblech und der Anlageflansch gegen die Kontaktierungselemente 1 6 gepreßt (siehe gestrichelte Darstellung der3 shows an application example of the tension clamp 10 according to the invention. In this drawing, a floor frame 20 is shown, which has a horizontal support section 21. Two profile sides 22, 23 are bent at right angles from the support section 21. A contact flange 24 is bent from the inner profile side 23. A bottom plate 25 can be placed on this with its edge. The base plate 25 can be clamped to the contact flange 24 by means of a plurality of clamps 10. The U-shaped clamp is mounted so that the edge of the bottom plate 25 and the contact flange 24 comes to rest between the two legs 1 1, 1 2. When the screw 1 7 is tightened, the base plate and the contact flange are pressed against the contacting elements 1 6 (see dashed illustration of FIG
Schraube 1 7) . Infolge der Einbringung einer Spannkraft in die Schraube 1 7 graben sich die Kontaktierungselemente 1 6 mit ihren Schneiden in die Unterseite des Anlageabschnitts 24 ein. Damit wird eine elektrisch leitende Verbindung zwischen der Spannklammer 10 und dem Bodenrahmen 20 hergestellt. Gleichzeitig ist auch die Schraube 1 7 auf die elektrisch leitende Oberseite des Bodenbleches 25 auf- gesetzt, so daß auch hier eine elektrisch leitende Verbindung entsteht. Damit lassen sich das Bodenblech 25 und der Bodenrahmen 20 auf ein gleiches elektrisches Potential legen. Screw 1 7). As a result of the introduction of a clamping force into the screw 1 7, the contacting elements 1 6 dig into the underside of the contact section 24 with their cutting edges. This creates an electrically conductive connection between the clamping bracket 10 and the floor frame 20. At the same time, the screw 1 7 is also on the electrically conductive upper side of the base plate 25. set so that an electrically conductive connection is also created here. The base plate 25 and the base frame 20 can thus be placed at the same electrical potential.
